jungle cactus in the Mexican state of veracruz

biosphere reserve ..... the tuxtlas

I made a rest trip to the jungle, a very nice temperature of 29 degrees, many rivers, some waterfalls, very beautiful tropical vegetation and some cactus that I share with you

Those orchids look very snug in that tree! Cool photos

i show you

in that tree there are orchids, ripsalis, bromeliads and a cactus similar to aporocatus

It is a heavenly place if you like heat and humidity

Very interesting dinfelu, I grow a few species epiphytic cacti. These are usually overlooked by most cactophiles in favour of the large flowered Epiphyllum or Orchid Cactus hybrids, but I prefer natural species every time.

Looked up Los Tuxtulas on the Internet and there is a site listing both plant and bird species, but as usual they tend to ignore the cacti. This was all I found listed:-

Rhipsalis baccifera

Selenicereus (Deamia) testudo

Your first picture looks like Rhipsalis baccifera.

The Cereus in the second and third does not look like Deamia testudo though, but a Selenicereus?

Don't think your "Epiphyllum" is an Epiphyllum, but something more like an Acanthocereus since it has muli-ribbed stems. Species Epiphyllum's have two ribbed flat leaflike flat stems. The multi angled stems in the Epiphyllum hybrids, or Orchid Cactus, come from the hybridising of them with Heliocereus. Whether your second to last picture is the same I do not know, but could be a young Deamia.

Deamia (now lumped into Selenicereus) is very characteristic in it's method of flattened growth tightly clasping the tree.

there is a very close place that manages the National Autonomous University of Mexico, which is called the Tropical Biology Station "Los Tuxtlas"
It is a paradise, the jungle in full, all kinds of life is protected within this season,
One of the waiters who assisted us lives in the area and told us about a snake that was passing along the road, its thick and long body, something impressive

I leave a link, hopefully and enjoy it

now I show you my Rhipsalis baccifera already has several years in my garden
the cactus of photo no.2 was identify for a lady but not with the scientific name but as it is known
there ..... cactus dog tail
very short thorns, their roots were stuck to the bark of the tree I think it is a daenia testudo

I read with interest the links you leave me and I appreciate your comments

Young hylocereus seedlings growing on trees are often very thin and spiny and do not look like the mature plants. It they survive they eventually sent roots down the trunks to the ground after which they make major growth. Photos 2 and 3 look like hylocereus, and the other foto with the plant in the ground does look more like acanthocereus.

Rhipsalis Baccifera is the most widespread cactus in the world, growing from the Americas across Africa to Sri Lanka. It is common in all the higher elevation locations here in northern Nicaragua.
